Breakthrough air conditioning heating performance

Mitsubishi Electric introduces a breakthrough in air conditioning heating performance with the introduction of a hyper-heating series. Unlike conventional air conditioning systems, the MSZ-FB VAH does not loose heating capacity when it is cold outside.

A Mitsubishi Electric hyper-heating Heat Pump will deliver the same amount of heat whether operating at 7°C or –15°C.

The Mitsubishi Electric hyper-heating Heat Pump Range is fitted with an advanced compressor that allows superior heating performance, even in sub zero temperatures. The key to its superior performance is the Mitsubishi Electric “Heat Caulking” compressor technology that allows larger amounts of refrigerant to be moved around the system using less energy.

Air conditioner energy label

The star rating for air conditioners is determined from the measured EER and COP. From 2010, for cooling, 1 star is equal to an EER of 2.75 with an extra star for an increase in EER of 0.5. For heating, 1 star is also equal to a COP of 2.75 with an extra star for an increase in COP of 0.5 Importantly, the 2010 star rating system is based on an annual efficiency calculation which includes any non-operational energy consumption such as standby and power consumption of crank case heaters (where present).

Air Conditioner MEPS

Since October 2004, all single phase air conditioners have been required to meet Minimum Energy Performance Standards (MEPS), which specify minimum levels of energy efficiency for these products. All three phase air conditioners have been required to meet MEPS since October 2001. Revised MEPS levels were introduced in April 2010 and these will again be upgraded in April 2011. You can find details of the current and future MEPS levels for air conditioners on the web page that describes MEPS for air conditioners in detail.

The Energy Rating Label has two main features:

• The star rating gives a quick comparative assessment of the model's energy efficiency
• The comparative energy consumption (usually kilowatt hours/year) provides an estimate of the annual energy consumption of the appliance based on the tested energy consumption and information about the typical use of the appliance in the home. Air-conditioners show the power consumption of the appliance (kW or kWh/hour).

The Star Rating of an appliance is determined from the energy consumption and size of the product. These values are measured under Australian Standards which define test procedures for measuring energy consumption and minimum energy performance criteria. Appliances must meet these criteria before they can be granted an Energy Rating Label.
